Leviticus 1:4-8

And he shall lay his hand on the head of the burnt offering, so that it may be accepted for him to make atonement on his behalf.

Then he shall slaughter the bull before the Lord; and Aaron’s sons the priests shall offer up the blood and sprinkle the blood around on the altar that is at the doorway of the tent of meeting.

He shall then skin the burnt offering and cut it into its pieces.

And the sons of Aaron the priest shall put fire on the altar and arrange wood on the fire.

Then Aaron’s sons the priests shall arrange the pieces, with the head and the suet, on the wood which is on the fire that is on the altar.
